TO ALL WHOM I'I MAY ONCERN:

Be it known that I, NATHAN S. CLEMENT, of New Britain, in the county ofHartford, in the State of Connecticut, have invented certain newanduseful improvements in Handles for Awls and analogous tools; and I dohereby declare that the following is a full and exact descriptionthereof. Y

My device -seizes and liberates the awl by opening and closing a dividedsocket, This general mode of construction has been long known, but myinvention is different from any before known to me, and superiorthereto.

I will iirst describe what I consider'the best means of carrying out myinvention, and will afterwards designate the points which Ibelieve to benew. -The accompanying drawingsform a part'of, this specification.

Figure I is a central longitudinal section.

Figure 2 is a View of the rear-end.

Figure 3 is a section showing on a larger sca Similailetters of'reference indicate like parts in all the iigures.

A isthe main body of the handle. It is perforated through its axis toreceive the steel or iron stein B, and is recessed toward the rear, asindicated by A, to form a receptacle for the tools which are not in use.is a cover for this receptacle. It also containsa metallic nut, c, whichfits on the threaded end' of the' stein Il, as indicated. This nut c isstar-shaped on its outer surface, as shown in iig. 2, and is' larger,both at its inner end and outer end, than along the centre of itslength. It is formed of type metal, or analogous material, and is castin place. p The process of forming it consists in putting the cover C ina proper positionl in sand or in a mould, andv after inserting the stemB, or, by preference, a highlypolished steel former made ofcorresponding shape, the type metal is poured in until the mould'or thecavity is full. After the metal is chilled the stem B or correspondingformer is removed by unscrewing it, and the surfaces of the metal c aresubsequently finished by'hanfl or by machinery. The opposite end of thestem B is split for a considerable distance, as indicated by The stem isalso formed with a tapering head, as indicated by B. 'lhe splitbreceives a nail or wire which is driven through the handle andthroughthe split after the stem is put in its proper position in the handle.The tapering head B fits to the corresponding interior of the ferrule D.This fcrrule is secured on the handle A by embracing it for a littledistance, the surface of the handle being formed irregularly, so as tolock with lthe corresponding shaped ferrule, as indicated in thedrawing. The ferrule D is cast in place by means similar to that justdescribed for the production of the nut c. -A small amount oflongitudinal motion of the stein B is allowed, by driving the nail orwire a little above the lower end of the split ,It will, of course, beunderstood that a suitable socket i-s formed for the awl or other tool,and that this socket coincides in position with the split Z1, but is notas deep. The socket is square in section.

The parts of my handle being properly put together, the' cover C isturned in such direction as to partially unscrew the nut c from thescrew on the stem Il. It is then'pushed forward so as to carry the stemwith it, and this, by pushing out or protruding the tapering front endof the stem B beyond the ferrulc D, allows it to spring open a little.The awl E is now inserted in its proper position, and the cover C isscrewed in the opposite direction, so as to draw the stem B into the nutc. This movement draws the tapering part B down into the tapering socketin the ferrule D, and causes it to be pressed together with such forceas to confine the awl E. In this condition the tool may be used for anylength of time, and the reverse of thel above-described operation willliberate the awl and allow the handle to be lcarried in the pocket, orallow the tools :o be changed at pleasure.

I do not claim separately the divided and tapering stem 'B B', operatingas represented, nor thc nut e, nor the handle and cover A C. I do notclaim anything shown in the patent issued to D. II. Chamberlain, datedle the mode of joining the fcrrule and handle.

. May 30, 1848, but having now fully described my invention, what Iclaim as new therein, and desire to secure by Letters Patent, is asfollows:

I claim'as a new article of manufacture the awl handle 'hereindescribed, having a tapering head, B, on a movable stem, operated` by anut, c, locked in 'the cover C, by being headed or enlarged to match therecesses provided in said cover, as herein set forth.

N. S. CLEMENT.
